Cardiovascular diseases （CVD），a group of common diseases in clinical practice，are witnessing a steady rise in both incidence and mortality rates，posing a challenge to public health. Gualou Xiebai Banxiatang，originating from Synopsis of the Golden Chamber （《金匮要略》），was initially used to treat severe cases of chest impediment. The formula consists of Trichosanthis Fructus，Allii Macrostemonis Bulbus，Pinelliae Rhizoma，and Baijiu. It has a wide range of clinical applications，with therapeutic effects including moving Qi to relieve depression，activating Yang to dissipate mass，and expelling phlegm to alleviate chest congestion. In recent years，clinical research has confirmed that Gualou Xiebai Banxiatang，with or without modification，used alone or in combination with Western medicine，has definite effects in the treatment of CVD such as hyperlipidemia，coronary atherosclerotic heart disease，hypertension，heart failure，and arrhythmia. It can alleviate disease symptoms and reduce the risk of re-hospitalization. Basic research indicates that the mechanisms of Gualou Xiebai Banxiatang include improving endothelial functions，exhibiting anti-inflammatory properties，countering oxidative stress，preventing apoptosis，inhibiting ventricular remodeling，regulating mitochondrial functions，improving hemorheology，and modulating autophagy and neurotransmitters. This article reviews relevant articles in recent years with focuses on the compatibility，clinical application，and mechanism of Gualou Xiebai Banxiatang. This review is expected to provide a theoretical basis for the mechanism research and clinical application of this formula in treating CVD and to offer ideas and reference for in-depth research.

Objective To compare the hemodynamic effects of anesthesia induction with remimazolam tosylate and etomidate in elderly frail patients.Methods This study was a single-center,prospective,randomized,single-blind trial.From January to April 2024,96 elderly frail patients undergoing elective surgery in Fuyang People's Hospital were recruited.After excluding 6 cases(3 refused to participate,1 had tracheal intubation time＞30 s,and 2 had missing data),90 patients were finally included.They were randomly divided into remimazolam tosylate group(intravenous injection of 0.2 mg/kg remimazolam tosylate for anesthesia induction,n=45)and etomidate group(intravenous injection of 0.3 mg/kg etomidate for anesthesia induction,n=45)by the random number table method.The area under the curve for mean arterial pressure(MAP)below or above baseline values(AUCMAP-and AUCMAP+),the heart rate(HR)below or above baseline values by 10％(AUCHR-and AUCHR+)within 10 minutes of anesthesia induction,the time to loss of consciousness,the time from the start of anesthesia induction to a bispectral index(BIS)＜60,the incidence of drug-related adverse reactions,the incidence of cardiovascular adverse events,and the usage of vasoactive drug administrations were compared between the two groups.Results Compared with the etomidate group,the AUCMAP-(145.10±35.75 vs.178.52±39.78)and AUCHR-[43.20(26.58,56.35)vs.54.99(43.01,65.85)]in remimazolam tosylate group were significantly reduced(P＜0.001,P=0.001).The time to loss of consciousness and the time from the start of anesthesia induction to BIS＜60 were prolonged(P＜0.001).The incidence of drug-related adverse reactions was significantly decreased(P＜0.05),and the number of norepinephrine administrations was significantly reduced(P＜0.05)in remimazolam tosylate group.However,there were no statistically significant differences in AUCMAP+,AUCHR+,the incidence of cardiovascular adverse events,and the usages of atropine,urapidil,and esmolol between the two groups(P＞0.05).Conclusion The use of remimazolam tosylate during anesthesia induction in elderly frail patients can provide more stable hemodynamic parameters and results in fewer adverse reactions than etomidate.

ObjectiveTo compare the clinical features of patients with hepatitis B virus （HBV）-related early-onset liver cancer and those with late-onset liver cancer， to assess the severity of the disease， and to provide a theoretical basis for the early diagnosis and treatment of liver cancer. MethodsA retrospective analysis was performed for 695 patients who were diagnosed with HBV-related liver cancer for the first time in Guangzhou Eighth People’s Hospital， Guangzhou Medical University， from January 2019 to August 2023， among whom 93 had early-onset liver cancer （defined as an age of50 years for female patients and40 years for male patients） and 602 had late-onset liver cancer （defined as an age of ≥50 years for female patients and ≥40 years for male patients）. Related clinical data were collected， including demographic data， clinical symptoms at initial diagnosis， comorbidities， smoking history， drinking history， family history， routine blood test results， biochemical parameters of liver function， serum alpha-fetoprotein（AFP）， virological indicators， coagulation function， and imaging findings. The pan-inflammatory indices neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， and lymphocyte-to-monocyte ratio （LMR） were calculated， as well as FIB-4 index， aspartate aminotransferase-to-platelet ratio index （APRI）， S index， Model for End-Stage Liver Disease （MELD） score， Child-Turcotte-Pugh （CTP） score， albumin-bilirubin （AIBL） grade， and Barcelona Clinic Liver Cancer （BCLC） stage. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or Fisher’s exact test were used for comparison of categorical data between two groups. ResultsThere were significant differences between the two groups in the proportion of male patients and the incidence rates of diabetes， hypertension， and fatty liver disease （χ²=6.357， 15.230， 11.467， and 14.204， all P0.05）， and compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly higher proportion of patients progressing to liver cancer without underlying cirrhosis （χ²=24.657， P0.001） and a significantly higher proportion of patients with advanced BCLC stage （χ²=6.172， P=0.046）. For the overall population， the most common clinical symptoms included abdominal distension， abdominal pain， poor appetite， weakness， a reduction in body weight， edema of both lower limbs， jaundice， yellow urine， and nausea， and 55 patients （7.9%） had no obvious symptoms at the time of diagnosis and were found to have liver cancer by routine reexamination， physical examination suggesting an increase in AFP， or radiological examination indicating hepatic space-occupying lesion； compared with the late-onset liver cancer group， the patients in the early-onset liver cancer group were more likely to have the symptoms of abdominal distension， abdominal pain， and jaundice （all P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly larger tumor diameter （Z=2.845， P=0.034）， with higher prevalence rates of multiple tumors and intrahepatic， perihepatic， or distant metastasis （χ²=5.889 and 4.079， both P0.05）， and there were significant differences between the two groups in tumor location and size （χ²=3.948 and 11.317， both P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had significantly lower FIB-4 index， proportion of patients with HBsAg ≤1 500 IU/mL， and levels of LMR and Cr （all P0.05）， as well as significantly higher positive rate of HBeAg and levels of log₁₀ HBV DNA， AFP， WBC， Hb， PLT， NLR， PLR， TBil， ALT， Alb， and TC （all P0.05）. ConclusionCompared with late-onset liver cancer， patients with early-onset liver cancer tend to develop liver cancer without liver cirrhosis and have multiple tumors， obvious clinical symptoms， and advanced BCLC stage， which indicates a poor prognosis.

The paper introduces one case of intractable beriberi treated with acupuncture of He's three-promotion needling method. The patient visited the hospital because of "repeated redness and swelling of the feet, combined with itching for over 2 years, aggravated in recent 2 days on the left foot". The chief complaints included redness and swelling of the left foot, with the normal walking disturbed, poor appetite, and abdominal distention after meal. The case was identified as beriberi (downward flowing of damp heat, and dysfunction of spleen in transportation due to deficiency). In treatment, using the fire needling technique of acupuncture, Bafeng (EX-LE10) on the left side were stimulated (warming-promotion method). The blood drops were squeezed in the local, if less bleeding was presented, the three-edge needle was used to prick the local area where the acupoint located (strong-promotion method). Afterward, the regular acupuncture was delivered at bilateral Yinlingquan (SP9), Zusanli (ST36) and Sanyinjiao (SP6), as well as Yanglingquan (GB34) and Xuanzhong (GB39) on the left side (mild-promotion method). The therapeutic regimen was adjusted flexibly according to the changes of the symptoms. After treated for 3 weeks, the symptoms disappeared.

This article systematically reviews the characteristics and trends of the writing, editing, publication and promotion of physiology textbooks in China from the late 19th century to the present, focusing on the introduction, development and innovation of Chinese physiology textbooks. The development of physiology textbooks in China is divided into four main stages: the introduction and initial development of physiology textbooks from the late 19th century to 1925; the localization and diversification of textbooks from 1926 to 1949, after the establishment of the Chinese Physiological Society; the exploratory phase of textbook construction after the founding of the People's Republic of China from 1949 to 1976; the formation and innovation of the textbook development process from 1977 to the present, following the restoration of the college entrance examination. For each phase, the article not only records the historical development of physiology textbooks, but also analyzes the evolution of their content, writing styles and the interaction with the social and political contexts. The article summarizes the characteristics and experiences of all these four phases. Special attention is given to the comprehensive statistical analysis of physiology textbooks published since the restoration of the college entrance examination and Economic Reform and Opening-up in 1977, revealing the changes in the number, publication trends and academic features of textbooks during this period. Finally, the article presets the future development of physiology textbooks in China, proposing that textbook writing should integrate aspects such as ideological and political education, medical humanities, basic and clinical medicine, health education, scientific research and international exchange and collaboration. The article also advocates for the application of new technologies and methods, such as artificial intelligence, virtual teaching models and knowledge graphs, to support "personalized learning". This research provides a systematic reference for the study of the history of medical education and offers theoretical support for the future innovation of physiology textbook in China.

Andrographolide sulfonate (AS) is a sulfonated derivative of andrographolide extracted from Andrographis paniculata (Burm.f.) Nees, and has been approved for several decades in China. The present study aimed to investigate the novel therapeutic application and possible mechanisms of AS in the treatment of rheumatoid arthritis. Results indicated that administration of AS by injection or gavage significantly reduced the paw swelling, improved body weights, and attenuated pathological changes in joints of rats with adjuvant-induced arthritis. Additionally, the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1β in the serum and ankle joints were reduced. Bioinformatics analysis, along with the spleen index and measurements of IL-17 and IL-10 levels, suggested a potential relationship between AS and Th17 cells under arthritic conditions. In vitro, AS was shown to block Th17 cell differentiation, as evidenced by the reduced percentages of CD4⁺ IL-17A⁺ T cells and decreased expression levels of RORγt, IL-17A, IL-17F, IL-21, and IL-22, without affecting the cell viability and apoptosis. This effect was attributed to the limited glycolysis, as indicated by metabolomics analysis, reduced glucose uptake, and pH measurements. Further investigation revealed that AS might bind to hexokinase2 (HK2) to down-regulate the protein levels of HK2 but not glyceraldehyde-3-phosphate dehydrogenase (GAPDH) or pyruvate kinase M2 (PKM2), and overexpression of HK2 reversed the inhibition of AS on Th17 cell differentiation. Furthermore, AS impaired the activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signals in vivo and in vitro, which was abolished by the addition of lactate. In conclusion, AS significantly improved adjuvant-induced arthritis (AIA) in rats by inhibiting glycolysis-mediated activation of PI3K/AKT to restrain Th17 cell differentiation.

OBJECTIVE: Recent studies have overturned the traditional concept of the lung as a "sterile organ" revealing that pulmonary microbiota dysbiosis and abnormal surfactant proteins (SPs) expression are involved in the progression of silicosis. This study aimed to investigate the relationship between abnormal SPs expression and dysbiosis of lung microbiota in silica-induced lung fibrosis, providing insights into mechanisms of silicosis. METHODS: Lung pathology, SPs expression, and microbiota composition were evaluated in silica-exposed mice. A mouse model of antibiotic-induced microbiota depletion was established, and alveolar structure and SPs expression were assessed. The roles of the lung microbiota and SPs in silicosis progression were further evaluated in mice with antibiotic-induced microbiota depletion, both with and without silica exposure. RESULTS: Silica exposure induced lung inflammation and fibrosis, along with increased expression of SP-A expression. Antibiotics (Abx)-induced microbiota depletion elevated SP-A and SP-D expression. Furthermore, silica exposure altered lung microbiota composition, enriching potentially pathogenic taxa. However, antibiotic-induced microbiota depletion prior to silica exposure reduced silica-mediated lung fibrosis and inflammation. CONCLUSION Lung microbiota is associated with silica-induced lung injury. Overproduction of SP-A and SP-D, induced by Abx-induced microbiota depletion, may enhance the resistance of mouse lung tissue to silica-induced injury.

AIM To explore the effects of Dahuang Lingxian Recipe on Th1/Th2 cell immune imbalance in a rat model of cholestatic liver fibrosis(CLF).METHODS 20 SD rats were randomly divided into the normal group,the model group,the ursodeoxycholic acid group(0.063 g/kg)and the Dahuang Lingxian Recipe group(4.8 g/kg),with 5 rats in each group.Except for those of the normal group,the rats of all other groups had open surgery of common bile duct ligation,followed by the gavage of corresponding drug two days later,and the procurement of the samples after gavage in the third week.The rats had their degree of liver fibrosis observed by HE and Masson stainings;their levels of serum total bile acid(TBA),alkaline phosphatase(AKP),γ-glutamyltransferase(γ-GT),alanine aminotransferase(ALT),aspartate aminotransferase(AST)and total bilirubin(TBil)measured by the kit;their hepatic percentage of TGF-β1,p-Smad2 and p-Smad3 positive cells detected by immunofluorescence and immunohistochemical staining;their.hepatic expressions of TGF-β1,Smad4,NF-κB p65,Collagen Ⅰ and Collagen Ⅲ protein and mRNA detected by Western blot and RT-qPCR;their levels of helper T cell 1(Th1)and helper T cell 2(Th2)in peripheral blood detected by flow cytometry,and their ratio of Th1/Th2 calculated as well.RESULTS Compared with the model group,the groups intervened with either ursodeoxycholic acid or Dahuang Lingxian Recipe displayed well-ordered liver cells,hepatic lobules and hepatic cords;a small amount of fatty degeneration;significantly reduced connective hyperplasia of hepatic fibers;significantly narrowed fibrous cords;a small amount of blue fibrous septa;greatly improved pathological injuries including inflammatory infiltration of central vein and portal area;decreased levels of serum TBA,TBil,AKP,γ-GT,ALT and AST(P＜0.05);decreased hepatic expressions of TGF-β1,p-Smad2 and p-Smad3(P＜0.05);decreased hepatic expressions of TGF-β1,Smad4,NF-κB p65,Collagen Ⅰ and Collagen Ⅲ protein and mRNA(P＜0.05);and increased counts of Th1 cells in peripheral blood,decreased counts of Th2 cells,resultsing increased Th1/Th2 ratio(P＜0.05).And an even better effect was observed in the Dahuang Lingxian Recipe group.CONCLUSION Dahuang Lingxian Recipe can reduce or reverse CLF by inhibiting hepatic stellate cell activation through maintaining Th1/Th2 cell immune balance via the NF-κB/TGF-β1 signaling pathway.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Objective:To investigate the temporal correlation between occupational stress and elevated blood pressure among petroleum workers in Xinjiang.Methods:Based on the Occupational Health Study Cohort of Petroleum Workers (OHSPIW), 1600 petroleum workers in Xinjiang who underwent occupational health examinations from May to June 2015 and December 2017 were selected as the research subjects. The occupational stress of workers was evaluated using the Occupational Roles Questionnaire (ORQ) in the Occupational Stress Inventory-Revised (OSI-R). The blood pressure measurement data of physical examination results were collected. The relationship between the ORQ total score and blood pressure was analyzed using Spearman rank correlation, and the causal time-series relationship between occupational stress and elevated blood pressure over time was analyzed by cross-lagged path analysis modelling.Results:In the baseline data of petroleum workers, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 124.00 (119.00, 128.00) and 77.00 (73.00, 82.00) mmHg respectively, with an ORQ total score of 164.00 (154.00, 174.00) points. In the follow-up data, the SBP and DBP were 126.00 (123.00, 128.00) and 78.00 (75.00, 82.00) mmHg respectively, and the ORQ total score was 168.00 (157.00, 181.00) points. The results of the correlation analysis showed that the ORQ total score of petroleum workers was positively correlated with the levels of SBP and DBP ( P<0.05), and the ORQ total score at follow-up was negatively correlated with the baseline levels of SBP and DBP ( P<0.05). The results of the cross-lagged path analysis showed that the path coefficients from the baseline ORQ total score of petroleum workers to the follow-up SBP and DBP levels were statistically significant ( ρ=0.06, 0.06, P=0.032, 0.011). In terms of time sequence, the increase in the ORQ total score preceded the increase in the SBP and DBP levels. Conclusion:The occupational stress of petroleum workers is related to blood pressure, and the increase of occupational stress precedes the change of blood pressure. This correlation may increase the risk of hypertension among petroleum workers.
